<h3>Background</h3> Deucravacitinib is a first-in-class, oral, selective, allosteric tyrosine kinase 2 (TYK2) inhibitor approved in multiple countries for the treatment of adults with plaque psoriasis. Deucravacitinib suppresses signaling of cytokines involved in the pathogenesis of immune-mediated diseases including psoriasis, psoriatic arthritis, and systemic lupus erythematosus. Deucravacitinib was efficacious compared with placebo in phase 2 trials in psoriatic arthritis and systemic lupus erythematosus.<sup>[1,2]</sup> In two phase 3 trials in patients with moderate to severe plaque psoriasis (POETYK PSO-1 [NCT03624127], PSO-2 [NCT03611751]), deucravacitinib showed superior efficacy versus placebo and apremilast.<sup>[3,4]</sup> Upon completion of either psoriasis trial, patients could enroll in the POETYK long-term extension (LTE) trial (NCT04036435). <h3>Objectives</h3> To evaluate the incidence rate and severity of adverse events (AEs) due to COVID-19 with deucravacitinib treatment in the POETYK PSO-1 and POETYK PSO-2 trials and open-label POETYK LTE trial. <h3>Methods</h3> In PSO-1 (N=666) and PSO-2 (N=1020), adult patients with moderate to severe plaque psoriasis were randomized 2:1:1 to deucravacitinib 6 mg once daily, placebo, or apremilast 30 mg twice daily. At Week 16, placebo patients in both trials switched to deucravacitinib. Based on their Week 24 PASI response, apremilast patients continued with apremilast or switched to placebo or deucravacitinib. In PSO-1, patients randomized to deucravacitinib continued treatment for 52 weeks; in PSO-2, some patients randomized to deucravacitinib had a randomized treatment withdrawal period. At Week 52, patients could enroll in the open-label LTE and receive deucravacitinib. Incidence rates and severity of COVID-19–related AEs in the POETYK trials (n=1364; 2076.7 person-years [PY] of follow-up) were compared with the Janssen/Johnson &amp; Johnson COVID-19 vaccine trial placebo group (n=19,544; 3096.1 PY of follow-up). This reference population was selected due to the study design and timing of the trial, which occurred when variants were in circulation. <h3>Results</h3> As of October 1, 2021, 1519 patients received ≥1 dose of deucravacitinib over a 2-year follow-up period; 1364 patients met criteria for this analysis, with deucravacitinib exposure since the pandemic onset (estimated to be January 1, 2020). In total, 153 deucravacitinib patients reported a COVID-19–related AE, for an overall exposure-adjusted incidence rate (EAIR) of 7.4/100 PY (95% CI, 6.2–8.6). Serious COVID-19–related AEs occurred in 43 patients (EAIR, 2.1/100 PY; 95% CI, 1.5–2.8), including 30 with COVID-19 and 13 with COVID-19 pneumonia; this rate was within the margins of those for moderate to severe COVID-19 reported in the reference population (EAIR, 16.5/100 PY; 95% CI, 15.0–17.9). Deaths due to COVID-19 occurred in 6 patients (EAIR, 0.3/100 PY; 95% CI, 0.1–0.6), with the COVID-19–related mortality rate being consistent with the reference population (EAIR, 0.23/100 PY; 95% CI, 0.1–0.5). Treatment was discontinued due to COVID-19 or COVID-19 pneumonia in 7 patients, including the 6 patients who died due to COVID-19. <h3>Conclusion</h3> COVID-19 was among the most frequently reported AEs during the 2-year period of the pooled PSO-1, PSO-2, and LTE trials due to the temporal overlap of the pandemic with the trials. However, COVID-19 infection and death rates did not differ from the reference population; most infections were not serious and did not lead to treatment discontinuation. Based on this analysis, deucravacitinib did not appear to increase the risk of COVID-19 nor its progression to severe outcomes. <h3>References</h3> [1]Mease PJ, et al. <i>Ann Rheum Dis</i>. 2022;81:815-822.
